Xandrox is made by Dr. Lee, and he sells spironolactone too. Xandrox is his own recipe of minoxidil... with or without propylene glycol (an irritant to some people), or with a dht inhibitor.
Don't go with anything other than what is proven to work in the beginning though. Propecia can be bought with a prescription from a pharmacy, rogaine (or any generic form) can be bought over the counter, and nizoral shampoo can be bought at any general store.
Try these for at LEAST a year before saying they don't work.
